Data acquisition and signal processing system based on TMS320C50 and on a IMSA100 processing cascade

A data acquisition and processing modular architecture, based on the TMS320C50 digital signal processor (DSP) and a cascade for four IMSA100 processors is presented. The system consists of up to four similar IBM PC boards, capable of simultaneous data acquisition. Each board has a fast acquisition front end, which is user configurable to one, two, or four independent input channels, with acquisition rates of 100, 50, and 25 MSPS (mega samples per second), respectively, the resolution being 8 bits. The complete system can be configured to a maximum of 16 acquisition channels operating simultaneously at a 25 MHz rate.<<ETX>>
